3.3.2 Elastic and Inelastic Collisions – Check yourself

Submit quiz
Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?
1.
In an inelastic collision
momentum is not conserved
momentum is conserved but kinetic energy is not
kinetic energy is conserved
energy is destroyed
2.
For a perfectly elastic collision in one dimension, the relative speed of approach
is double that of separation
is half that of separation
equals the speed of separation
is zero
3.
A 3.0 kg object at 4.0 m s-1 sticks to a stationary 1.0 kg object. The kinetic energy lost is
18 J
12 J
6.0 J
24 J
4.
Equal masses collide elastically head-on, one stationary. After the collision
the first stops and the second moves with the original speed
both move together
both rebound
the first continues at half speed
5.
Which is true in an explosion starting at rest?
kinetic energy is conserved
kinetic energy decreases
momentum increases
kinetic energy increases
6.
Which could NOT be a collision outcome in an isolated system?
total kinetic energy decreases
total momentum increases
objects stick together
kinetic energy is unchanged
